Vaillant ecoTEC plus VU 486/5-5 48 kW

Single-circuit heating gas boiler of high power, designed for wall mounting. The main distinguishing feature of this model is the highest efficiency, due to the use of the condensing principle of extracting heat from natural gas combustion products. Unlike simple boilers, in this design, hot flue gases are subjected to deeper cooling, which makes it possible to extract from them the latent heat of condensation of water vapor formed directly in the combustion process.

This engineering solution allows the Vaillant ecoTEC plus VU 486/5-5 condensing boiler to save up to 6% natural gas (compared to classic boilers of the same power). This model uses a closed-type combustion chamber with forced exhaust of flue gases. This design allows you to abandon a separate boiler room and mount the boiler directly in residential areas. The useful power of the device is enough to heat a large private household, commercial, domestic or industrial premises with a total area of up to 384 m2. The boiler is equipped with a quiet two-stage circulation pump, an automatic air vent and a digital information and analytical control system. It can work in combination with a DHW tank and a branded room thermostat equipped with a weekly programming system.
